Cleaning Solutions

Do not use alcohol, gasoline, bleach, mineral acids, solutions with a flash point,

semi-aqueous or combustible liquids in ultrasonic tanks, or you will void the

warranty. Only use non-flammable solutions and water-based solutions.

Water-based solutions are either slightly acidic or alkaline. They include detergents,

soaps and industrial cleaners designed to remove specific soils.

Acidic water-based solutions: remove rust, tarnish or scale. They range from mild

solutions that remove tarnish, to concentrated, and inhibited acidic solutions that

remove investment plaster, milk-stone, zinc oxide and rust from steel and cast iron as

well as smut and heat-treat scale from hardened steel.

Alkaline water-based solutions: include carbonates, silicates and caustics. These

cause emulsifying action, which keeps soil from redepositing on the cleaned surface,

and improves cleaning action in hard water.

Change the cleaning solution periodically. Cleaning solutions can become

contaminated with suspended soil particles which coat the tank bottom. This coating

dampens the ultrasonic action and reduces cleaning efficiency. Certain solutions will

cavitate better than others. Contact your local distributor for further information.

Heat and cavitation: increase the chemical activity of cleaning solutions. Some

materials may be damaged by this stronger chemical action. When in doubt, test run

samples of items to be cleaned. Caustic solutions: used to remove rust from steels,

metal alloy corrosion and a variety of tenacious soils.

Solution amounts may vary. The amount you use depends on the detergent and the

type of soil to be removed. Follow instructions on the solution container and refer to the

table below for the effects of solutions on metals.

CAUTION

Removes:

Light oils and greases, cutting oils and coolant compounds.

Heavy grease and oil, waxes, vegetable oils, inks, wax or fat-

base buffing and polishing compounds, milk residues and

carbohydrates.

Mill scale; heat-treat scale, corrosion or oxides.
